Etymology: Chelidoperca: Greek, chelidon, -onos = swift, as black as a swift + Greek, perke = perch (Ref. 45335); microdon: Name from Latin meaning small-toothed, referring to its lack of enlarged canines on both
jaws..

Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 10; Mjukstrålar i ryggfenan (totalt) : 10; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 6. This species is distinguished by the following set of characters: pored lateral line scale rows 42; (dorsal-most scale full-sized) scale rows between lateral line and middle of spinous dorsal fin base 3; absence of scale rows on ventral side of dentary; interorbital scales are mostly
cycloid, beyond the level of anterior pupil rim, but not reaching the anterior orbit rim; the 5 rectangular dark blotches at or slightly above the lateral line are usually retained; 2 dark blotches on tip of lower jaw (Ref, 123218).p
Along the COI gene, the following apomorphic sites have unique nucleotides shared by the two specimens of C. microdon examined so and these nucleotide sites so far can be used for the diagnosis of the species to other congeners (Ref. 123218).
This rare and deep-water species occurs on the continental shelf (Ref. 123218).
